here you go!!! :))) this took a lot of time but i gotchu!!
Answer:
12.5 cm
Step-by-step explanation:
To find the distance, set up a proportion. A proportion is two equal ratios set equal to each other. We form the ratios by using corresponding values. We write a ratio of and simplify.
We know . We also know
.
We set them equal.
To find the width on the map, we cross multiply numerator and denominator.
Answer: 5 , 4.5
Step-by-step explanation:
Answer: 1.8
Step-by-step explanation:
First option is wrong because using a scale factor of 1 would result in the same shape.
Second option is wrong because using a scale factor less than 1 would result in shape 2 becoming smaller.
Third option is most likely as shape 1 looks almost double the size of shape 2.
Fourth option is unlikely because shape 2 would have to expand more than 4/3 to be as large as shape 1.
Fifth option is wrong because the scale factor cannot be less than 1.
Answer: y = 4x + 5
Step-by-step explanation:
The general equation of a line is y = mx + d ,
m = slope
d indicates the y-intercept, when x=0 , Y=5 => (0,5)
In the given line m = 3 , so that is the slope.
This slope has an angle = arctan(3) = 71.56º
If we need a steeper line, we have to increase m,
By example y = 4x + 5 , would have the same y-intercept but would be steeper.
This new line has a greater slope, with an angle = arctan (4) = 75.96º
